The Japanese Concept of Animal Poop

I don't know what the deal is, or whether many Japanese people had traumatic experiences with animal poop as children, but whatever the cause, the outcome is a disproportionate presence of animal poop warning signs. These signs employ vivid imagery and expressive faces to get the point across.

This one I found in a park near the church.

Poop Sign 2
Ryan took a picture of this on his camping trip in Hokkaido.
Lit. "Beware of seagull poop."
